制作openssh的rpm升级包

本文主要是介绍制作openssh的rpm升级包，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

制作openssh的rpm升级包

1. 检查本机openssh版本，查看yum源中最新的版本

ssh -V
yum info openssh

2. 建立目录下载源码包

cd /root
mkdir -pv rpmbuild/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}
wget https://openbsd.hk/pub/OpenBSD/OpenSSH/portable/openssh-8.2p1.tar.gz -O rpmbuild/SOURCES/openssh-8.2p1.tar.gz

3. 开始制作

解压拷贝文件

cd  rpmbuild/SOURCES
tar xf openssh-8.2p1.tar.gz
cp openssh-8.2p1/contrib/redhat/openssh.spec   ../SPECS
cd ../SPECS/

按需修改以下内容：

vi openssh.spec
# Do we want to disable building of x11-askpass? (1=yes 0=no)
%define no_x11_askpass 1 
# Do we want to disable building of gnome-askpass? (1=yes 0=no)
%define no_gnome_askpass 1

使用rpmbuild制作rpm包，完成后在RPMS下生成rpm安装包

rpmbuild -bb openssh.spec

如果提示缺乏依赖,执行下载所有依赖包，可以打包上传到服务器安装,这里以openssl-devel举例

yum install yum-utils -y
yumdownloader openssl-devel --resolve --destdir=../SRPMS

升级

mkdir /opt/backup
mv /etc/ssh /opt/backup
cp /etc/pam.d/sshd /opt/backup/sshd.pam
yum -y install ./openssh*.rpm
mv /etc/ssh/sshd_config{,.old_$(date '+%s')}
cat > /etc/ssh/sshd_config << SSHDEOF
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key
PermitRootLogin yes

AuthorizedKeysFile  .ssh/authorized_keys

mv /etc/pam.d/sshd{,.old_$(date '+%s')}
cp /opt/backup/sshd.pam /etc/pam.d/sshd
service sshd restart
